(54)	Mutant microorganismexpressing oxygenase, processes of degrading organic compounds and remediation of the environment, using it

(57) A mutant microorganism capable of degrading organic compounds without any inducer,
wherein the microorganism expresses oxygenase constitutively, and is a mutant derived from a parent microorganism capable of expressing an oxygenase enzyme with an inducer, by mutagenization using a mutagen, and a process for degrading organic compounds and remedying environment using the microorganism, as well as a process for detecting a microorganism constitutively expressing oxygenase among oxygenase-inducible microorganisms.
